The goal is to pass through all the dots with only 4 lines. You may need to think outside the box! If you need a tip go down to the bottom. I recommend trying it without first. Carful there will be a useful tip down there, try to do it without. Can't do it? Think outside the box, literally.
I made this game based on a real known puzzle, I don't know where it came from but it definitely might leave you stumped. This is the first project in a mini puzzle series I am starting. Check out my other games too! https://scratch.mit.edu/studios/31156643
